Relay Output for Weighing Scales – Hi / Lo / OK Weight Triggers
Price on Request
Relay output add-on for an existing scale (HSCo or most makes): Hi/Lo/OK weight triggers to switch fillers, valves, conveyors and alarms. Single or multiple relays, fitted by HSCo.
The HSCo relay output module adds weight-based switching to a scale you already own, whether HSCo or most other makes. Set Hi, Lo or OK limits, and the scale switches a relay to start or stop a filler, open a valve, stop a conveyor or sound an alarm. We fit and configure it to your system, with single or multiple relay outputs.
What it lets your scale do
- Programmable triggers. Hi / Lo / OK weight limits.
- Control other equipment. PLCs, motors, valves, buzzers and more.
- Single or multiple relays to suit your process.
- Works with most scales: platform scales, hoppers, tank weighing systems and custom units.
- Fitted and configured by HSCo.
